More than 91% of Costa Ricans receive potable water in their homes and part of the efforts to achieve this reality, and improve it even further, have historically been supported by the Central American Bank for Economic Integration (CABEI).

Currently, five initiatives are being implemented, including projects and programs comprised of specific works that seek to promote the country's social wellbeing, not only by improving public health and hygiene among citizens, but also by strengthening the social fabric by guaranteeing access to essential basic services.

The strategic collaboration between the country's authorities and CABEI has been crucial for implementing innovative and sustainable water management solutions, both in the increase and construction of works, as well as in proper sanitation and sewerage.

CABEI's commitment reflects a proactive approach to climate resilience and environmental sustainability, positioning its founding member country Costa Rica as a model to follow in water resource management.


  1. Water Supply Program for the Metropolitan Area of San José, Urban Aqueducts and Sanitary Sewerage of Puerto Viejo de Limón:
    • This program includes the construction of an integrated aqueduct system for Ciudad Neilly, Canoas, Laurel and Vereh in the southern part of the country, as well as improvements to the sanitary sewer system in Puerto Viejo de Limón and the implementation of a sludge treatment system for the water treatment plant in Miraflores de Pérez Zeledón. In addition, the increase and improvements to the Ciudad Cortés aqueduct will benefit more than 167,000 people.

  2. Water Supply Program for the San José Metropolitan Area, Urban Aqueducts II and Juanito Mora Sanitary Sewage System in Puntarenas:
    • This program encompasses eleven essential projects, including improvements to water supply systems in different regions of the country, such as Pérez Zeledón, Alajuela and San José, as well as the construction of collectors and improvements to wastewater treatment plants in Puntarenas, benefiting more than 551,000 people.

  3. Non Revenue Water Reduction and Energy Efficiency Project (RANC-EE):
    • This project aims to optimize operations related to water management in aqueducts and improve energy efficiency in pumping stations in order to reduce unaccounted-for water and improve existing infrastructure. More than 5 million people will benefit from these improvements.

  4. Potable Water and Sanitation Program for Coastal Areas, Service Quality and Efficiency Management:
    • This program includes several works to improve the supply of potable water in coastal areas, such as Guácimo, Quepos - Manuel Antonio and Jacó, benefiting more than 269,000 people. In addition, the construction of the National Water Laboratory is foreseen.

  5. Sewerage and Flood Control Program for Limón:
    • This program includes the construction of flood control systems in Limoncito and the expansion of the sanitary sewer system in central Limón, benefiting more than 300,000 people.


For CABEI, environmental sustainability and compliance with high standards that guarantee the correct use of natural resources as part of the development of the projects it finances is crucial. That is why, as part of some initiatives, reforestation activities are contemplated to compensate for the environmental footprint that may have been generated as part of the operations.
